Figure 8.

Grafting Followed by ICP-MS Analysis Indicates That Loss of Function of NaKR1 in the Shoot Tissue Is the Main Cause of the nakr1-1 Na⁺/K⁺ Overaccumulation Phenotype.

(A) The different grafting types. From left to right are Col-0 shoot-Col-0 root, nakr1-1 shoot-nakr1-1 root, Col-0 shoot-nark1-1 root, and nakr1-1 shoot-Col-0 root.

(B) Shoot Na⁺ content in different grafting types and control plants. Data are presented as mean ± se.

(C) Shoot K⁺ content presented as mean ± se; n = 9 to 12 plants for grafting between Col-0 and nakr1-1, and n = 5 for self-grafting types and control plants (Col-0 and nakr1-1). Student’s t test was performed, and different letters in (B) and (C) indicate P values < 0.01.
